I give this three stars, taking away two for the bad sound quality. It sounds like music on a cheap AM radio in the next room.
Don't get me wrong. The performances are great, and every Ra album is important.
I especially like the rare vocal version of "China Gate," hitherto available on the studio "Futuristic Sounds" album issued a year later, in 1961. "China Gate" is a kind of Vaughn Monroe thing, but Ra was into exotic foreign settings at that time, like some of Les Baxter's records. It's historically interesting in retrospect because Ra was so avant garde elsewhere.
If you are not a collector, you are better off buying any of the 15 or so excellent CDs issued by Evidence Records and available from Amazon.
